The statement that is NOT valid is 4. System testing must begin once most components are code complete.
Explanation: While it is important for many components to be ready for system testing, system testing can begin even if not all components are fully complete, as long as a functional part of the system can be tested. In contrast, integration testing must occur first to ensure that components work together before completing system testing.
